Feeding your plant with nutrients is not just enough. The pH levels of the nutrient solution should regularly be monitored to ensure optimal utilization of the nutrients by the plant. As you may already know, the pH is the measure of the acidity or alkalinity of the nutrient solution. It is measured from 0-14, a pH of under 7 is acidic, above seven is basic, and seven is neutral. In a hydroponic setup, the ideal pH for absorbing nutrients is between 5.8 and 6.4. If the pH is too high, certain metals like iron may become unavailable to the plant, and if too little, the uptake of calcium, magnesium and other macro elements may be affected. As you can see, it is critical to monitor pH Control in a Hydroponic Setup.

In a hydroponic setup, regulating pH is easy. If the pH is too high, add little dilute acid like phosphoric acid to reduce it. If the pH is too low, adding a base such as potassium hydroxide to increase the pH. For most strains of marijuana, a pH of 6.0 is perfect. Commercially prepared pH buffer mixtures are readily available in safe, easy-to-use preparations.

For a perfect result, monitor the pH daily. Cheap pH test kits specifically designed for hydroponics, are available at most hydroponic retailers or can be gotten online… like here at PerryPhernalia.com!. To carry out a pH test, simply take a take a small sample of the nutrient setup and add a few drops of the pH indicator solution ). The color change on doing this and its value on a color chart will tell you the pH. If you want more
accurate readings, a pH meter will be ideal. Although pH meters are much easier to use, they are more expensive and require periodic calibration. Most growers do just fine with inexpensive pH kits as long as the pH readings fall between 5.8 and 6.4.
As with most things, pH Control in a Hydroponic Setup takes minimal time, but can help with a much better yield of your plants.
